结果：1）枯萎卵妊娠的胎囊内只有囊液，没有胚胎组织。 妊娠囊外没有绒毛组织或绒毛组织较稀疏。

Results:1) There is no embryonic tissue in gestation sac without or with little villous tissue in anembryonic pregnancy.

除了在本研究中利用基因调控网络中的小鼠胚胎干细胞的优势外，深入研究必须更加直接地集中于人类干细胞。

Despite the advantages of using mouse es cells in the study of gene regulatory networks, further research must focus more directly on human stem cells.

为胚胎发育早期绒毛外滋养层细胞侵袭的基因调控机制的研究提供了实验基础。

This study would help us to reveal the mechanism of gene network regulation in EVT invasion in early embryo development.

The way we did this was to coax embryonic stem cells first to develop into the surface layer.

我们是这么做的,先诱导胚胎干细胞,发育成外胚层。

We can see the early signs of ear development Start with the thickening of the outer layer of the embryo, this layer is called the ectoderm.

大家知道，耳朵发育的早期特征,是胚胎外层膜的增厚，这层膜也叫外胚层。
